I was totally freaking out over this same thing and posted a similar question elsewhere. I am now a week out of surgery and everyhting went fine. My diet was a bit different though. I had protein shakes and 2 protein bars a day, then like broth, jello, popsicles, etc. But 2 other people in my office had the same surgery as me with the same docs and their diets were the same except the doc told them they could have non-starchy veggies like carrots bellpeppers, lettuce and onion sometimes too. I did that sometimes and also cheated pretty bad maybe 3 times(cinco de mayo taco, a cheeseburger, and a few bites of mcdonalds ) during the diet and I was still fine. I still lost 15 lbs on the pre-op diet. So I wouldn't worry too much. Not that I am saying you should cheat all the time but I wouldn't lose any sleep over it.
